Examples: Expansion implemented using DTDs

This section of the specification contains examples of extension modules that are implemented using DTDs.

Example: Adding an element to the section element using DTDs
In this scenario, a DITA architect wants to modify the content model for the <section> element. The DITA architect wants to add an optional <sectionDesc> element that is specialized from <p>.
Example: Adding an attribute to certain table elements using DTDs
In this scenario, a company makes extensive use of complex tables to present product listings. They occasionally highlight individual cells, rows, or columns for various purposes. The DITA architect wants to implement a semantically meaningful way to identify the purpose of various table elements.
Example: Adding an existing domain attribute to certain elements using DTDs
In this scenario, a company wants to use the @otherprops attribute specialization. However, they want to make the attribute available only on certain elements: <p>, <div>, and <section>.
Example: Aggregating constraint and expansion modules using DTDs
The DITA architect wants to add some extension modules to the document-type shell for topic. The document-type shell already integrates a number of constraint modules.
